Engine v5.1.3
June 22, 2026
A patch in the Connection line.
what's new
- Savi can now notice and help fix visual effects, interface panels, sounds, and other game behavior that fails only on a player's device.
- Games with lots of changing primitive shapes render more efficiently.
- Savi now builds more consistent 2D character animations without swapping the character's visual identity between movements.
›technical notes
- Restored client-realm behavior fault reporting by routing effect, creator UI panel, vibe audio, and client-side
applySpecfailures through theengine.diagnosticrail to Savi. - Coalesced primitive batch buffer updates in
IndirectBatchedMeshso repeated changes are uploaded together instead of issuing redundant GPU buffer updates. - Updated the 2D creation skill and animation examples to keep one sprite identity while expressing motion through mixer clip slugs.
